You can play Destiny 1 but because of the Destiny 2 ban - you're given less leeway on other Bungie games and can be banned for less on them. [quote]Restrictions Across Destiny Releases: Players -blam!- a restriction or ban in one of our games will not be restricted/banned in our other games, unless they also have a ban or restriction applied for that game. However, players who have ever been banned or restricted in any Bungie game are considered high-risk players and are eligible for bans and restrictions at lower thresholds than players who have never been banned or restricted.[/quote]https://safety.bungie.net/hc/en-us/articles/42308518654100-Bungie-Game-Account-Restrictions-and-Banning-Policies
